Frames in Semi-inner Product Spaces

Springer Proceedings in Mathematics and Statistics, 2015
The objective of this paper is to study the theory of frames in semi-inner product spaces. Several researchers have studied frames in Banach spaces by using the bounded linear functionals. Application of semi-inner product is a new approach to investigate the theory of frames. The notion of semi-frame is introduced in this new aspect.

Approximate Orthogonal Preserving Mappings on C-Semi-inner Product Space

Caliphate Journal of Science and Technology, 2021
In this research work, we study Birkhoff-James orthogonality in an arbitrary normed linear space X , and establish the orthogonal preserving mapping in C*-semi-inner product space. It has been observed that every mapping that preserves orthogonality is necessarily a scalar multiple of an isometry. We finally introduce approximate orthogonality and

A Notion of Angle using a 2-Semi-inner Product on the Space of p-Summable Sequences

International Journal of Mathematics and Computer Science
We introduce a 2-semi-inner product on the space of p-summable sequences. Using this 2-semi-inner product, we define the h_p-orthogonality and the h_p-angle between two vectors and discuss their properties. Moreover, we formulate the h_p-angle between two 2-dimensional subspaces that intersects a 1-dimensional subspace.
